Ford F-150 - 1997-2003 :: Error Codes - Misfire Detected On Cylinders 2 / 5 And 6
Dec 14, 2014
My wife and I received her father's 2002 F150 4.2 5 speed 2 wheel drive truck after his passing. He purchased new plug wires and wanted to replace them. So, this weekend I put in new plugs, plug wires, changed the air filter, and changed the oil and filter. Started up and ran really rough. Threw my code reader on after taking it around the block and found the following codes...
P0316 Misfire detected in first 1000 revs,
P0302 Cylinder 2 misfire,
P0305 Cylinder 5 misfire,
P0306 Cylinder 6 misfire.
New plugs were Motorcraft plugs, but had skinnier center compared to the ones that came out of truck.
Where do I start? What do I do? I am really confused as I have changed plugs and wires before and always had vehicle run better or same as before change.

Recently bought 98 f150 xlt 3 door 5speed 4x4 4.6l 230k miles for $1k was throwing misfire codes on 1,8,4,3 cylinders. Usually throws two cylinders at a time and never the same cylinders consecutively
Parts replaced:
coils...msd blaster
belden wire
motorcraft plugs...when i did these it ran perfect for a tank of fuel...18mpg no stumble
two cans seafoam through the tank
tank was dropped and drained
fuel filter
one can seafoam intake cleaner
3" exhaust from the Y pipe back
MAF cleaned
Previous owner said to have tested and cleaned injectors but I am not positive it was done... I don't think its mechanical because it wanders through the cylinders and when i changed the plugs it ran spot on. it gets worse the warmer the truck gets also.
injectors?
clogged small cats?
sensor?

Truck has been running rough and the check engine light was on so I decided to get the codes read and I got back P0302 and P0304, which from what I understand is a misfire on cylinders 3 & 4. At the same time I got Ford to do a little diagnostic and this is what they wrote for me:
"The connector for the number 2 coil is broken and will not stay plugged on to the coil and the number 2 coil is not working / replaced the wire for the coil still running rough removed the coil and plug. the plug was very badly fuel soaked started the vehicle to see if there was spark at the plug. OK. Suspect either a injector issue or a compression issue cleaned the plug seems better. "
So of course they quoted me for the works. They say I should replace the coils, plugs, and injectors???
I am pretty mechanically inclined and think I could change these things myself since I am on a budget. One tech told me is that the plugs can seize in these engines often and could scrap the whole thing??? Seems a little weird. If that happens though what could I do?

I recently found these codes. My car is APR 1+. The car seems to run fine so I'm not sure what is going on. I changed the plugs at ~60K miles and now have 72K miles.

I am getting P0355 error code and potential misfire codes on all cylinders. Engine light and VSC stays on now. Idle is unstable and power is a little jerky at times. I bought a Denso direct ignition coil to replace, however, Cyl 5 looks difficult to access.

Where do I start? Pull the coil?

My 97 F-150 has 208,000 miles on the original engine. It started misfiring originally on just 2 cylinders, 1 and 8, after pulling the codes. I also get a P0420, catalyst system below threshhold bank code being thrown, but I think it is because of the misfires.
To remedy this I've done the following:
1. Spark plugs are relatively new and were changed completely a few months prior to issues.
2. Coil Packs were changed on both sides. Additionally, Cylinders 1 and 8 are on separate coil packs.
3. Spark Plug wires were changed
4. Did a resistance test on each fuel injector and they all passed.
None of this has worked. Am I missing something obvious? From my friends I've heard everything from my exhaust is plugged to I need to change all my injectors. Injectors are costly and I'm not even sure how to check if my exhaust is partially plugged, but it seemed to be flowing fine. Also, I pulled plug one since it was simple to get to and noticed it was slightly brown, like it had oil on it.
I got frustrated and continued driving my truck until the problem degenerated into severe misfiring and now I cannot get it started at all (Wrong move). I bought a car and haven't drove it since, and have it sitting behind my house. Now the cops want to tow it because the registration is has expired so I've decided to move it into my garage so I can work on it. Part of me wants to junk it, but I've put a lot of time, money, blood, sweat, tears, and curse words into this truck and am motivated to get it back up and running since the transmission and front suspension had been replaced recently.
What to do!?!?
1. Go to the Ford dealership and have them diagnose the issue and then try to fix it? (I have little confidence in them from the stories I've heard)
2. Pull the engine, tear it apart, and rebuild it?
3. Drop a used/rebuilt engine in?
4. Call me crazy and say junk the truck and buy a different one?
Currently leaning towards option 3...

I started out with misfires in cylinders 1 and 7. Replaced all spark plugs (used autolites, i know i know). While replacing them I found that the boot on coil 8 was beat up with a chunk missing. It was working before I replaced plugs. After I changed everything out the 8th quit working completely and I still had a miss in cylinder 1.
Replaced coils on both of those and put a new wire connector on for 8th cylinder because it no longer clicked in correctly anymore. Truck runs infinitely better than it did prior to this, but according to OBD2 I still have misfires in 1 and 8.
Mostly in the 50-60mph range. What else could be causing this??? Injector maybe or is there some other sensor or timing problem? My dad has a compression test kit, but he lives several hours away so I can't just get to that right away.

So the past few weeks my truck has been sputtering a lot. It seems to do it more so in low RPMS but when I lay on the throttle I didn't really notice it. I haven't had time to look into the issue but yesterday the issue got drastically worse and the CEL finally came on. Registered P0174 as well as a number of other codes including misfires on 7 of the 8 cylinders.
So far I have replaced the fuel filter. Spark plugs are only a few months old. I didnt think it would make sense for all of the coil packs to go out at once so I was thinking either a fuel issue or vacuum leak. Why would it only spit out P0174 (Banks 2) and not show P0171 (Banks 1) along with it? Fuel pump? Vacuum leak? Where should I start? 2002 F150 5.4L...

I bought a gorgeous red 4.0L V-6 Mustang very cheap last week because it needed a clutch. I would not even pull the car. Little did I know that the clutch kit, including the slave cylinder and flywheel, was over $600. (But that's another story.)
The car runs now, but will not go over 3800 RPM in any gear. It had NINE codes, which they cleared. I was told that they primarily pointed to the MAF sensor. I cleaned it with the recommended aerosol. I have driven it 20 miles, and the MIL has not returned, but the little wrench symbol has. The Manual says to take it to the dealer (of course). The car seems to run fairly well, with the exception of the low rev limit. It is a "fly by wire" set up, with electronic throttle.
The cleared codes were P0102, P0113, P0135, P0141, P0155, P0161, P0403, P0443, and P0446. They actually repeated on Autozone's scanner. (My six year old Actron won't link to this car for some reason.

I bought my first VW about 3 months ago (so excited!) It's a 2003 Passat, 5 spd, 1.8t. I've had one thing happen so far (until yesterday). On 4 separate occasions when I'd go to start it, it would crank for a few seconds before it would start. Then once it was running the EPC light would turn on. It seemed to be running normally but I turned it off and restarted it and it started normally and the light extinguished (the first three times). The last time (about a week and a half ago) it kept doing it each time I started it, and upon starting probably the 4th time in a row the MIL came on. I drove it about a mile, turned it off for a few minutes, then turned it back on and it started normally with no malfunction lights on. It's been normal since then. Until yesterday...
Yesterday as I'm accelerating from a stop light (I think I was in 3rd) all of the sudden the engine started running really rough and the MIL came on. I turned around and drove about 2 miles back to where I started at about 20mph. The MIL would be steady while coasting and flash while pressing the accelerator. I got a hold of a diagnostic computer and it came up with 3 codes...
1) P0322 Ignition/Dist Engine Speed Input Circuit No Signal
2) P0302 Cylinder 2 Misfire Detected
3) P0302 Cylinder 2 Misfire Detected PENDING

I do not know the 5.4l 3v as well as my last 360ci dodge. It's a 2005 F-150 SuperCrew 4x4, got it cheap, and it's got issues. Got codes for misfire on cylinders 4 and 5 and Coil 'D' circuit malfunction. Obviously it has codes for limited power as well. was wondering how cylinder numbering goes and what coil is 'D'.

So i got a 98 passat sedan used and was told it read a p0411 code. The person at autozone told him it was a cam sensor. The sensor was replaced. I know now from the manual that codes reads for sec. Air injection system , incorrect flow. It could be the vacuum lines. Now lets say it is the vacuum lines. Their is a misfire on cylinders 1-3.

I have been having odd problems with my truck for several weeks now and what the problem may be. Occasionally the truck will not start. This happens after it has been run for an errand or to church. The truck turns over but no ignition. Sometimes if I pump the gas pedal very quickly I can get it to start. Other times I have to sit and wait about 5 minutes. I have gotten the following two error codes - P1506=Cylinder Head Temp Sensor and P1299=Idle Air Control Overspeed Error. For two days the "check engine" light was on, but now it has gone out. I have searched for an answer to this problem on these boards and one possibility may be a vacuum leak. Is this the most likely? 1998 Triton 4.6 ....

I am having problems with a 2003 Ford F 150 with a 4.2 L V6. The problem is that it is giving me code errors that would indicate bad O2 sensors. I replaced both the upper and lower O2 sensors, and still I get the same codes. I was told by the mechanic with the computer reader that this usually means a bad vacuum seal. He suggested looking for bad hoses, but did not offer much more than that. How to proceed?

2001 f 150 5.4 liter with it being code pops up saying cylinder one misfire, I've charge coil and spark plug ran great for awhile now starting to act up again. Got coil check and says still good and look at spark plug and looks still in good shape being just replace two weeks ago. It's running fine but if it sits over night and I get in and start it and begins to shake when I but it in drive and don't even need to move the truck just place it in drive with foot on break. I drive it awhile and it stops and runs fine?
